android - BottomSheetDialogFragment AdjustResize SoftInput 不起作用

Question

嘿，我目前正在尝试使用以下布局创建一个 BottomSheetDialogFragment:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

                android:visibility="visible"/>
        </android.support.design.widget.TextInputLayout>
        <View
            android:id="@+id/albumEditDivider"
            android:layout_width="match_parent"
            android:layout_height="0.2dp"

            app:layout_constraintStart_toStartOf="parent"/>
    </com.indico.recorder.views.DonkeyConstraintLayout>
    <android.support.constraint.ConstraintLayout
        android:id="@+id/album_edit_activate"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clickable="true"
        android:focusable="true"
        android:padding="16dp"
        android:background="@drawable/capture_selection_item_background">
        <ImageView
            android:id="@+id/album_edit_activate_icon"
            android:layout_width="32dp"
            android:layout_height="32dp"

        <TextView

            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            />
    </android.support.constraint.ConstraintLayout>
</LinearLayout>

此处的目的是使出现的软输入调整大小并锚定在整个布局下方，而不是平移到 edttextfields。基于对如何使其与 fitSystemWindows 一起工作的大量研究和其他窗口属性导致我所有的 Bottom Sheet 都采用以下样式:

<style name="BottomSheet.Theme" parent="Theme.Design.Light.BottomSheetDialog">
        <item name="bottomSheetStyle">@style/BottomSheet.Style</item>
        <item name="windowNoTitle">true</item>
        <item name="android:label">@null</item>
        <item name="android:fitsSystemWindows">true</item>
        <item name="android:windowFullscreen">false</item>
        <item name="android:windowSoftInputMode">adjustPan|stateVisible</item>
        <item name="android:windowClipToOutline">true</item>
    </style>

    <style name="BottomSheet.Style" parent="Widget.Design.BottomSheet.Modal">
        <item name="behavior_peekHeight">300dp</item>
        <item name="android:background">@drawable/squared_card_background</item>
        <item name="behavior_hideable">true</item>
        <item name="android:windowFullscreen">false</item>
        <item name="android:windowSoftInputMode">adjustPan|stateVisible</item>
    </style>

我没有指定 windowSoftInputMode在 list 中，因为应用程序的其余部分需要默认行为。

Bottom Sheet fragment :

class AlbumCreateSheet: BottomSheetDialogFragment(), View.OnClickListener {

    companion object {
        private val tag = AlbumCreateSheet::class.java.simpleName
        fun show(fragmentManager: FragmentManager) {
            return AlbumCreateSheet().show(fragmentManager, tag)
        }
    }

    private lateinit var titleView: EditText
    private lateinit var descriptionView: EditText

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        dialog.window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)
        return inflater.inflate(R.layout.sheet_album_create, container, false)
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        titleView = view.findViewById(R.id.album_create_title)
        descriptionView = view.findViewById(R.id.album_create_description)

        view.findViewById<View>(R.id.album_create_create).setOnClickListener(this)

    }

    override fun onClick(v: View?) {
        when(v?.id) {
            R.id.album_create_create -> {
                useDefaultRealm {
                    executeTransaction {
                        val session = Session(name = titleView.text.toString(),
                                description = descriptionView.text.toString())
                        it.insertOrUpdate(session)
                    }
                }
                dismiss()
            }
        }
    }
}

任何关于如何解决这个问题的提示，以及使软输入调整整个底部的大小都非常受欢迎:)

Answer 1

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
val dialog = super.onCreateDialog(savedInstanceState)

dialog.window?.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)
dialog.setOnShowListener {
    Handler().post {
        val bottomSheet = (dialog as? BottomSheetDialog)?.findViewById<View>(R.id.design_bottom_sheet) as? FrameLayout
        bottomSheet?.let {
            BottomSheetBehavior.from(it).state = BottomSheetBehavior.STATE_EXPANDED
        }
    }
}

return dialog
